Or you could do the math and do the color change. http://jsfiddle.net/rustyDroid/WRExt/2/

>     $('#bar').animate({ width: '300px' }, 
>     {
>         duration:10000,
>         easing:'linear',
>         step:function(a,b){
>             var pc = Math.ceil(b.now*255/b.end);
>             var blue = pc.toString(16);
>             var red = (255-pc).toString(16);
>             var rgb=red+"00"+blue;
>             $('#bar').css({
>                 backgroundColor:'#'+rgb
>             });            
>         }
>     })
>      });
